Stainless steel 316 shut-off valve

Overview

Stainless steel 316 globe valves are commonly used shut-off/regulating valves in industrial piping systems. Their core advantages and features stem from the combination of the excellent performance of 316 stainless steel and the functional characteristics of globe valve structures, making them particularly suitable for corrosive environments and high-precision control scenarios.Stainless steel 316 globe valves are widely used in the following industries: Chemical industry: shut-off and regulation of pipelines transporting chlorine solutions and organic acids; Marine engineering: valves for seawater desalination and ship ballast water systems; Food and pharmaceuticals: sanitary shut-off of fruit juices, pharmaceutical solutions, and sterile water; Oil and gas: high-pressure shut-off of oil and gas extraction and transportation pipelines; New energy: transportation pipelines for lithium-ion battery electrolytes (containing fluorides).

 

Features

Good throttling characteristics: The flow path of the globe valve is ‘S’-shaped, resulting in a smooth change in flow velocity as the medium passes through. The valve stem travel is approximately linearly related to flow rate, enabling precise flow control (e.g., feed regulation for chemical reactors, temperature control in thermal systems);
Moderate opening and closing torque: Compared to gate valves, globe valves have a shorter valve stem travel distance during opening and closing. Additionally, the 316 stainless steel valve stem has a smooth surface with low friction, facilitating manual or electric control.
Compact size and lightweight: Compared to gate valves of the same nominal diameter, globe valves have a more compact valve body structure, making them particularly suitable for applications with limited pipeline space (e.g., internal piping of equipment, ship engine rooms); Simple disassembly and maintenance: Most 316 globe valves use ‘flange connections’ or ‘threaded connections,’ and wear-prone components such as the valve core, valve seat, and packing can be disassembled and replaced individually without needing to remove the entire valve, reducing maintenance complexity.
